NileRed Extra turns scrap aluminum into a nanoscale landscape

Nigel's microscope demonstration approaches four million views while the channel takes a week off from new uploads.

Channel: NileRed Extra Story of Trari Newsroom

Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.

Things we can learn from the video

Press to jump

  1. 0:00An atomic force microscope probes a sample's surface physically rather than imaging it with light or electrons.
  2. 2:13Nigel selects a diamond-like carbon tip from the two types supplied with the microscope.
  3. 4:05A scrap aluminum block becomes a surface scan and a three-dimensional topographic model in Gwyddion.
  4. 8:26The measured sandpaper particles fall within what Nigel considers a realistic range for its advertised grit.
  5. 9:16Nigel proposes measuring nanoparticles for future ferrofluid synthesis.

Nigel puts a scrap block of aluminum under a microscope, then builds a three-dimensional map of its surface. The instrument doesn't rely on light or an electron beam to reveal the detail: its tiny tip physically probes the sample.

That June upload, "Touching things at the atomic level (I love microscopes)", is NileRed Extra's busiest video right now. Approaching four million views, it is drawing more daily viewing than either October's laser-welder introduction or July's experimental coin-making project. There were no new uploads this week, but the catalogue added roughly 560,000 views.

The microscope, lent by ICSPI, gets a suitably careful welcome: a weighted vibration-isolation table, a choice of scanning tips and software calibration before the aluminum test. Nigel later checks sandpaper, but the longer-term attraction is what the machine could do for chemistry. He names measuring nanoparticles for ferrofluid as one use, connecting the new equipment to the lab's material-making ambitions.

The audience grew modestly over the week, although daily viewing is below the channel's usual level. Among nearby science channels, ABC Science and Cosmoknowledge had larger weekly audiences, while NileRed Extra brought in more views than WeatherAdam and Just Have a Think.

Its coin project supplies another very specific reason to revisit the archive: impatient for a manufacturer's sample commemorating the main NileRed channel's subscriber milestone, the team decided to try making versions themselves with metals including lead, sodium and mercury.
